“…In addition to the results in [18,Theorem 1] and [14,Theorem 10.52], the quasiadditivity property has been considered in the Euclidean space R n for instance in [2,3] for Riesz capacities, and in [9,20] (q = p) and [12] (q ≥ p) for fractional capacities with the help of fractional Hardy(-Sobolev) inequalities. Sufficient conditions for different versions of (weighted) Hardy and Hardy-Sobolev inequalities, and hence also for the corresponding quasiadditivity, have been given for example in [8,14,17,19,21]; see also the references therein.…”
